Universe Today wrote:If you were to take all of the water on Earth â€” all of the fresh water, sea water, ground water, water vapor and water inside our bodies â€” take all of it and somehow collect it into a single, giant sphere of liquid, how big do you think it would be?

According to the U. S. Geological Survey, it would make a ball 860 miles (1,385 km) in diameter, about as wide edge-to-edge as the distance between Salt Lake City to Topeka, Kansas. Thatâ€™s it. Take all the water on Earth and youâ€™d have a blue sphere less than a third the size of the Moon.
